STEAM-RADIATOR.

Specification of Letters Patent.

Patented March 30, 1909.

Application filed March 23, 1908. Serial No. 422,758.

To all whom it may concern: c Be it known that I, Romrr VVARG, a c1t1- zen of the United States, and resident of` Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Steam-Radiators; and I do hereby declare that the following is a full, clear, and exact description thereof.

The object of my invention is to prevent air-pockets in steam radiators, and to also dispense with the necessity of maintaining a constant steam pressure in order to insure proper circulation.

The invention therefore consists in various details of construction and combination of parts as hereinafter set forth with reference to the accompanying drawings and subsequently claimed.

In the drawings: Figure 1 represents an elevation of a steam-radiator embodying the features of my invention, the view being partly broken away and in section, as indicated by line ll of Fig. 2, and Fig. 2, a sectional plan view of the same with parts broken away and parts in section, as indicated by line 22 of the preceding figure.

Referring by numerals to the drawlngs, 1 indicates a cast hollow radiator-base, which base is formed with transverse end-heads 2 and 2a respectively. The heads communicate with chambers 3, l, that are separated by a division wall 5, the base bottom 6 of each chamber heilig inclined from the divisionwall toward the heads to insure perfect drainage of condensation. The upper wall 7 of the chambers is provided with series of rows of tapped apertures grouped upon either side of the division wall 5. Into these apertures are fitted the ends of looped steam-pipes 8, the same being nested in rows with their vertical legs upon opposite sides of said division wall 5, whereby steam is circulated from one chamber to the other.

As shown in Fig` 2 of the drawings, two or more radiator bases with their looped pipes are preferably coupled together to constitute a complete radiator, although one section may be used with the same results where a small area of radiator surface is sufficient. With this in view the heads of each radiator base are provided with single transverse openings 9 and 10 respectively upon opposite sides, the openings constituting right and left steam inlet and discharge communication to the chambers. By

the above construction it is apparent that any number of the radiator' bases may be assembled in a battery in such relation that steam admitted to the first base, through its outside opening 9 will be compelled to pass from the adjacent chamber 9 through the looped pipes in the opposite chamber, and from there directly into the next radiator base by way of the communicating openings in the heads and so on until the steam has finally completed the circuit in a continuous zig-zag course through the entire battery. By this arrangement it will be seen that the steam passes directly through the radiator forcing the air ahead, the condensation being shed into the heads from which it is drained by drip-pipe 16.

In assembling the sections, the radiating base-heads having communicating openings are preferably provided with metallic paclr ing rings l1, which rings are interposed between the adjacent faced edges of the openings. The opposite ends of said radiator bases have closed abutting heads, between which heads are placed suitable rings 12, which serve as spacers. The outer or exposed head-cnds of the assembled bases are each provided with cap-plates 13 having apertures for clamping bolts 14, which bolts in connection with their nuts serve to draw the several sections together and maintain steam-tight connection therebetween.

The steam-inlet and discharge openings of the first and last sections of the radiator base have their capplates provided with threaded apertured openings 15 for the reception of steam-inlet and discharge pipes, the latter being either connected to another radiator' or open direct to the atmosphere.

From the foregoing description it will be understood, should the heating system be supplied by exhaust steam there would be no back-pressure upon the engine sup lying the exhaust, which exhaust would be .reely discharged from the last radiator to atmos phere. If live-steam is utilized any well known method of connection from the last radiator may be employed. Under either of these arrangements great efficiency and economy in heating is effected, while at the same time liability of the formation of airpoclrets in the pipes is eliminated, this result beinO due to the direct flow of steam.

filiere it is desired to carry steam-pressure in the system, the last radiator is provided with a closed dischargaend and a suitable :livrent valve in oriler to dispel air from .said system.

I claim:

steam radiator having' a plurality of parallel seetions, each of which sections comprises a longitudiiial hollow base having a ventral transverse dirisionwall thereiin hereby separate chambers are formed, the hotiolnwa1l of each chamber of each base- Seetion being inclined in opposite directions from its division-Wallr` said hollow hase being formed with a tra nsverse head in direct eonnnunication with the chambers of each of said hase-sections and eaeh of said heads being provided with openings communicating with the heads of adjacent parallel sections at alternate opposite ends of said Seotions, and a series of looped'pipes for each section` each series being connected to a section upon opposite sides of its division-Wall. ln testimony that I Claim the foregoing I have hereunto Set iny hand at Milwaukee, in the county of l\ffilwaukee and State of VViS- eonsin in the preaenee of two Witnesses.
